I saw this in The Straits Times a couple of days ago and I thought it might be interesting for some blog readers with children still in preschool. Undoubtedly, Science lessons start in Primary 3. If you wait until Primary 3 to give your children exposure to Science, you'll always be behind the curve. Start them off with these toys. They're just toys so there is no need to get all serious and boring.
Just let them play?
